Abstract
The utility model relates to an auto discharging vehicle lifting structure, particularly relating to a lower positioned oil chamber back pushing typed auto discharging vehicle lifting structure. The utility model comprises a wagon, a side rack, a triangle arm, a pulling bar and an oil chamber, wherein the back end of the wagon bottom rack is hinge connected with the side rack bottom end, the upper end of the triangle arm is hinge connected with the wagon bottom rack front end, the pulling bar lower end is hinge connected with side rack front end, the upper end is hinge connected with the triangle arm lower end, the upper end of the oil chamber is hinge connected with the middle portion of the triangle arm, and the lower end of the oil chamber is hinge connected with the front end of the side rack. The utility model has simple and reliable structure, good craft, good wagon cross stability, high lifting structure efficiency and big lifting ability.
Description
(1) technical field under
The utility model relates to a kind of tipper lifting mechanism, particularly a kind of underlying oil cylinder back-pushed tipper lifting mechanism.
(2) background technology
At present, tipper lifting mechanism mainly contains direct-push and linkage rod group box-like two big classes, and wherein linkage rod group is box-like multiple version again, all forms the car four-bar linkage by compartment, subframe, triangle arm, pull bar, use hydraulic oil cylinder driving four link works then, realize compartment upset self-unloading.Because structural limitations, the present box-like lifting mechanism of several linkage rod group all is positive four-bar linkage structure (the quadrangle interior angle all is not more than 180 degree), the fulcrum in lifting compartment is positioned at the middle part, compartment, the subframe boxed rod strong point is positioned at the subframe middle part, the compartment lateral stability is relatively poor in the lifting process, and oil cylinder stroke is little, and jacking capacity is less.
(3) summary of the invention
The utility model provides the underlying oil cylinder back-pushed that a kind of compartment lateral stability is good, jacking capacity is big, lifting efficiency is high tipper lifting mechanism in order to overcome above deficiency.
The utility model is realized by following measure:
Tipper lifting mechanism of the present utility model, form by compartment, subframe, triangle arm, pull bar and oil cylinder, underframe rear end, compartment and subframe rear end are hinged, triangle arm upper end is hinged with compartment underframe front end, pull bar lower end and subframe front end are hinged, upper end and triangle arm lower end are hinged, and the middle part of the upper end of oil cylinder and triangle arm is hinged, lower end and subframe front end are hinged.
Tipper lifting mechanism of the present utility model, optimized the connecting rod assembly frame mode, by the compartment, subframe, the triangle arm, pull bar is formed reverse-four-link-bar mechanism (quadrangle has an interior angle greater than 180 degree), make the fulcrum in lifting compartment move forward to compartment underframe front end, the subframe top rod strong point moves forward to the subframe front end, even the very long lateral stability that also can guarantee compartment in the lifting process in compartment, and the fulcrum in lifting compartment and the reach of the subframe top rod strong point, oil cylinder stroke is strengthened, the efficient of lifting mechanism is higher, compare with conventional linkage compound type lifting mechanism, jacking capacity improves 20-30%.
Using method of the present utility model is that when oil cylinder length increased, the reverse-four-link-bar mechanism that is made up of compartment, subframe, triangle arm, pull bar rotated, and realized compartment upset self-unloading.When the oil off-load, the compartment falls by deadweight, and lifting mechanism recovers initial position.
The beneficial effects of the utility model are, have simple and reliable for structure, good manufacturability, the compartment lateral stability is good, lifting mechanism efficient height, jacking capacity is big.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is made specific description.
Accompanying drawing is a structural representation of the present utility model
Among the figure, 1 subframe, 2 pull bars, 3 oil cylinders, 4 triangle arms, 5 compartments,
(5) specific embodiment
The concrete structure of present embodiment as shown in drawings.Be made up of compartment (5), subframe (1), triangle arm (4), pull bar (2) and oil cylinder (3), compartment (5), subframe (1), triangle arm (4), pull bar (2) are formed reverse-four-link-bar mechanism.Subframe (1) links into an integrated entity with car chassis, underframe rear end, compartment (5) and subframe (1) rear end are hinged, triangle arm (4) upper end is hinged with compartment (5) underframe front end, pull bar (2) lower end and subframe (1) front end are hinged, upper end and triangle arm (4) lower end are hinged, and the middle part of the upper end of oil cylinder (3) and triangle arm (4) is hinged, lower end and subframe (1) front end are hinged.
Claims (1)
1. underlying oil cylinder back-pushed tipper lifting mechanism, form by compartment (5), subframe (1), triangle arm (4), pull bar (2) and oil cylinder (3), it is characterized in that: underframe rear end, compartment (5) and subframe (1) rear end are hinged, triangle arm (4) upper end is hinged with compartment (5) underframe front end, pull bar (2) lower end and subframe (1) front end are hinged, upper end and triangle arm (4) lower end are hinged, and the middle part of the upper end of oil cylinder (3) and triangle arm (4) is hinged, lower end and subframe (1) front end are hinged.
